Figure 1. 2 year biologically no evidence of disease(bNED) versus prescription dose of 125I brachytherapy. The symbols represent the Fox Chase clinical data [1] and the curves represent the model calculations. The three points (circle, square and triangle), as well as the three curves (solid, dashed and dash-dotted), are for patient groups with hypoxic, mixed and aerated prostate tumours, respectively. The prescription dose of the clinical data was 145 Gy of 125I implant. The vertical dotted line indicates the prescription dose for the hypoxic group to achieve a bNED of 81%. The vertical error bar shows the standard confidence interval (CI) of the clinical data for the hypoxic group (the CIs for the other two groups are not shown) and the horizontal error bar shows the CI of dose escalation for the hypoxic group to achieve a target bNED of 81%.
